The rice bean is a small, hairy annual vine which bears yellow flowers and small edible beans. It is a minor food and fodder crop and occasionally a weed.
The English language name is a literal translation of the Chinese language name, fàndòu.
Seed colour is variable, but commonly red or yellow.
Although a separate species from the more common azuki bean, its appearance and uses are similar, though red type rice beans should be the correct ones.
